title: Ménétrier's disease associated with Kaposi's sarcoma.
abstract: Ménétrier's Disease is a giant fold gastropathy whose precise etiology has remained enigmatic. However, mucosal changes characteristic of Ménétrier's Disease have been linked to diverse pathologies, both infectious and malignant. Here, we describe a novel association: Ménétrier's mucosa developing on top of underlying Kaposi's Sarcoma. Two male patients, ages 24 and 31, with HIV/AIDS underwent gastric biopsies that demonstrated Kaposi's Sarcoma. When the former patient expired, a more complete postmortem histologic examination of his stomach was undertaken. For each patient, endoscopic findings at the time of biopsy revealed thickened gastric mucosa overlying the Kaposi's changes. Microscopically, this thickened mucosa comprised hyperplastic foveolar cells that extended to the muscularis mucosa, characteristic of Ménétrier's mucosa. In both cases, special stains confirmed this impression. Dissection of the 24 year-old patient's stomach at autopsy demonstrated that the Ménétrier's mucosa was limited to areas where there was underlying Kaposi's Sarcoma, and that this mucosa was not present when the underlying stroma was normal. Our findings indicate, therefore, an association between Ménétrier's mucosal changes and Kaposi's Sarcoma; such an association has not, to our knowledge, been described previously in the literature.
